GMS SLR Brake disc for Alfa Romeo Giulia and Stelvio Quadrifoglio are available in front as BBK (Big brake kit) 378mm x 32mm or standard 360mm x 32mm, and in rear as 350mm x 28mm. GMS SLR Brake discs feature true, fully floating design, which means that aluminum bells are not directly connected to the brake disc rotors as they commonly are. Instead, they slide within the bobbin grooves, making them much more capable of withstanding extreme thermal expansion without getting warped.
 
Discs feature J-hook grooved braking surface, providing significantly improved de-dusting capabilities and cracking resistance compared to OEM and aftermarket drilled discs. The brake disc ring casting is a high content carbon, heat treated alloy, with low expansion properties under heat stress to provide least possible thermal expansions during its operation. Each GMS SLR disc is also dynamically weight balanced to prevent potential vibrations at high speed.
 
Discs sizes allow to still fit 18'' wheels which makes a perfect track setup. We also didn't forget about the weigh and even though there is a significant improvement in braking performance over OEM brakes, the weight is only 9640g for front disc vs. 10414g OEM and 8490g for the rear disc vs. 8718g OEM. That's roughly 4kg of unsprung weight reduction on all four wheels combined.
 
As the disc wear on the track, especially on a heavy car like Giulia and Stelvio Quadrifoglio is significant, the brakes have to be overhauled or replaced often, so GMS SLR brake disc rotors are also available as a replacement part which saves the cost of replacing entire brake discs, as only brake disc rotors can be replaced instead.
